SPY. A never-ending Diagonal

The choices on how the uptrend will finish are very few to be honest: a common 1-2-3-4-5 structure or the so-called Ending Diagonal Triangle.

Experienced EW adepts may surely be able to correct me but I feel like the EDT it starting to become our main option. This means:

1) S&P will first climb to 2360-2370, then to 2450-2500.
2) The correction will bring the price close to Wave 1. In theory, they have to intersect but that would mean leaving the Diagonal´s limits way too far. However, the option of having the S&P at 2100 is there
3) We will probably have another ABCzigzag in the last wave up, which would may also be an Ending Diagonal

Whether this development is correct or not, I believe our target for S&P is somewhere at 2450-2500 zone.
